I was never an 'indie' but I also escaped in stages.
It took me about two and a half years (total) to figure out that this organization was not really what I wanted to be doing. I simply left the Sea Org. I won't say blow, they can blow me.
I wasn't declared. In fact, they called me up a couple of months later offering to let me work off my 'freeloaders debt' at ten bucks an hour helping to reno Flag. That turned out to be a complete fraud, but I've already covered that. I told them to shove the year contract after six months, when I learned about this (I should have sued them for the promised ten bucks an hour!). They bought my ticket home rather than hear from my personal injury attorney brother.
The point is; I still aspired to learning those great secrets that would allow me to exist separate from my mortal body, effect the world around me with just the power of will, etc. This is what was really promised using more...circumspect language.
You could say I was still 'in' in that I still didn't imagine that all those people on the upper levels, writing all those incredible 'success stories' in 'Advanced!' magazine could possibly be all lying, and there must be some great worth in this. It's just the people running it, not the Hubster, of course, were mucking it up somehow.
It only took me one sitting to read Bent Corydon's 'LRH, Messiah or Madman?' and I was completely cured.
It makes total sense to me why people first leave the organization, blaming it on the people they dealt with, and then later wind up leaving the philosophy (if you want to stretch the meaning of that word). They simply acquired more info that was skillfully withheld from them while they were in.
